Yes, it can define the symbols correctly.

Is the in_reg() checking for the reference in regular object? If so, will it be
more clear if we can check it first? like

    if (oldsym == NULL || !oldsym->in_reg())
      return NULL;
    if (oldsym->source() != Symbol::IS_UNDEFINED &&
        !oldsym->is_from_dynobj())
      return NULL;

Well, this is only my opinion.

Another question about the only_if_ref flag. Is it for the reference in regular
object? Looks like both reg/dyn symbols will go into the namepool, but we don't
check in_reg() previously.

Thanks.
